   name: MERS-CoV main protease (Mpro) activity fluorescence dose response biochemical assay
   description: |
-    This is a functional, biochemical assay used to identify treatments for viral infectious disease in MERS 3C-like main viral protease. 
-    Utilizing a direct enzyme activity measurement method, the experiment was performed in a 384-well plate reading the fluorescence intensity. This assay tested the mode of action of inhibition. 
+    This biochemical assay measures the inhibition of protease activity of the MERS-CoV main viral protease (Mpro), also known as the 3C-like protease (3CLpro).
+    It is suitable for high-throughput dose-response measurements in a 384-well plates for supporting drug discovery efforts against this target.
